The once Patented Acme, Lull & Porter hinge dates to around 1860. It is the most popular hinge in New Orleans. When the shutter is open, it is locked into place. A hold back or shutter dog is not required. When closing, the shutter is slightly lifted to allow it to pass over the locking part of the hinge joint. When fully closed, the shutter drops down into a locked position.
Cast iron and powdercoated. These may be purchased as a lower cost without powdercoat by request.
One side of the hinge is mortised into the edge of the shutter and the other is mortised into the window casement. Choose a hinge that gives you the best clearance away from the indow casement. Many offsets and throws available. Sets include 2 left handed, 2 right handed hinges, 2 sets of fasteners and mounting screws.

How to determine the offset
The offset is 1/2 the distance measuring from the face of the brick to where the shutter closes, generally the face of the molding or the window stop just inside. This puts the hinge knuckles at the corner as shown or projecting further out.
Shutter weight calculated using 2 hinges per shutter with a width no more than 24" and a height no more than 60" up to 75 lbs.
